Their eyes were heavy - That is, they could not keep them open. Was there nothing preternatural in this? Was there no influence here from the powers of darkness?

And he came and found them asleep again,.... For they were aroused and awaked, in some measure, by what he had said to them; but no sooner was he gone but they fell asleep again, and thus he found them a second time; or, "he came again and found them asleep"; so read the Vulgate Latin, the Syriac, Arabic, and Ethiopic versions, and Munster's Hebrew Gospel:

for their eyes were heavy; with sleep through fatigue, sorrow, &c. Mark adds, "neither wist they what to answer him", Mark 14:40; they were so very sleepy, they knew not how to speak; or they were so confounded, that he should take them asleep a second time, after they had had such a reproof, and exhortation from him, that they knew not what answer to make him; who probably rebuked them again, or gave them a fresh exhortation.

And he came and found them asleep again: for their eyes were heavy.

26:43 He came and found them asleep again. The motive of this return we may reverently believe to have been, as before, the craving for human sympathy in that hour of awful agony. Our Savior, we must not forget, was human as well as divine.

26:36-46 He who made atonement for the sins of mankind, submitted himself in a garden of suffering, to the will of God, from which man had revolted in a garden of pleasure. Christ took with him into that part of the garden where he suffered his agony, only those who had witnessed his glory in his transfiguration. Those are best prepared to suffer with Christ, who have by faith beheld his glory. The words used denote the most entire dejection, amazement, anguish, and horror of mind; the state of one surrounded with sorrows, overwhelmed with miseries, and almost swallowed up with terror and dismay. He now began to be sorrowful, and never ceased to be so till he said, It is finished. He prayed that, if possible, the cup might pass from him. But he also showed his perfect readiness to bear the load of his sufferings; he was willing to submit to all for our redemption and salvation. According to this example of Christ, we must drink of the bitterest cup which God puts into our hands; though nature struggle, it must submit. It should be more our care to get troubles sanctified, and our hearts satisfied under them, than to get them taken away. It is well for us that our salvation is in the hand of One who neither slumbers nor sleeps. All are tempted, but we should be much afraid of entering into temptation. To be secured from this, we should watch and pray, and continually look unto the Lord to hold us up that we may be safe. Doubtless our Lord had a clear and full view of the sufferings he was to endure, yet he spoke with the greatest calmness till this time. Christ was a Surety, who undertook to be answerable for our sins. Accordingly he was made sin for us, and suffered for our sins, the Just for the unjust; and Scripture ascribes his heaviest sufferings to the hand of God. He had full knowledge of the infinite evil of sin, and of the immense extent of that guilt for which he was to atone; with awful views of the Divine justice and holiness, and the punishment deserved by the sins of men, such as no tongue can express, or mind conceive. At the same time, Christ suffered being tempted; probably horrible thoughts were suggested by Satan that tended to gloom and every dreadful conclusion: these would be the more hard to bear from his perfect holiness. And did the load of imputed guilt so weigh down the soul of Him of whom it is said, He upholdeth all things by the word of his power? into what misery then must those sink whose sins are left upon their own heads! How will those escape who neglect so great salvation?
